STG Test Notes

NOTE: You should enter this Pinpoint Test only when the Switch Monitor Test Chart in Quick Test or a Component Verification Test directs you here.

REMEMBER: This Pinpoint Test is intended to diagnose only the following:

- Circuits: ACS (A/C On-Off Switch), BPS (Boost Pressure Switch), BLMT (Blower Motor Control Switch), CCPS (Clutch Cycling Pressure Switch), CPP (Clutch Pedal Position Switch), FAN (Cooling Fan Switch), HPS (High Pressure Switch), IDL (Idle Switch), PNP ([1][2]Park/Neutral Position Switch), PSP (Power Steering Pressure Switch), DEF (Rear Window Defroster Switch), WOT (Wide-Open Throttle Switch).

Clutch Pedal Position Switch:

Description: The Clutch Pedal Position (CPP) switch detects when the clutch pedal is depressed and signals the Powertrain Control Module (PCM) with input information.

Location: Mounted at the top of the clutch pedal.

Idle Switch:

Description: When the throttle plate is closed, an idle condition occurs. The Idle (IDL) switch detects this position and notifies the PCM with an input signal, so adjustments to the engine can be made, including air/fuel ratio and idle speed.

Location: Mounted to the throttle body.

Park/Neutral Position Switch:

Description: The Park/Neutral Position (PNP) switch detects whether the vehicle is in the NEUTRAL position. The switch informs the PCM of the transaxle's present condition.

Location: Threaded to the transaxle, on the bottom RH side.

Power Steering Pressure Switch:

Description: When the power steering fluid pressure exceeds the preset limit, the Power Steering Pressure (PSP) switch sends an input signal to the PCM, which then adjusts idle speed.

Location: Threaded into the power steering pump.
